MACHINE.

SPECIFICATION forming part of Letters Patent N0. 473,429, dated April 19, 1892. Application filed August 21, 1891. Serial No. 403,288.' (No model.)

To all whom t may concern.-

Be it known that I, PETER PHILLIPS, of the town of Toronto Junction, in the county of York, in the Province of Ontario, Canada, have invented a certain new and useful Improvement in Mitering-lllachines, ot' which the following is a specification.

f My invention relates particularly to a machine for cutting ruiters and kindred formations of wood; and the objects of the invention are, -first, to provide a machine to cut in a vertical plane, said vertical plane being readily adjustable to any desired angle with the direction of the work operated on; secondly, to provide a machine to out at any desired angle from the vertical plane and at the same time at a right or any desired angle to the Work.

I attain the above objects by means of the mechanism illustrated in the accompanying drawings, in which similar letters 0E reference refer to similar parts throughout.

Figure l is a perspective view of my xnachine, partially broken away to show the construction. Fig. 2 is a sectional detail showing the means of clamping the saw-frame at any angle desired. Fig. 3 is a detail in elevation of the table-adjusting mechanism.

In the drawings, A is the main frame of the machine, carrying a bed-plate B, which supports at its center a hollow cylindrical bearing C. On the bearing O is supported l the swinging frame D, which at its lower cychine.

lindrical portion is neatly tted over the bearing O and adj ustably secured thereon by bolts or thumb-screws passing through the slotted lugs E, which are fast to or form part of the swinging frame D. Atthe front of the bearing C is a scale of degrees as a guide to the angle of inclination of the frame D, right or left from. the initial or center line oi the ma- An index-pointer F, secured on the frame D at the front, is pro vided or any other suitable indicator. The frame D supports in suitable bearings the horizontal frame Gr, composed of the circular heads H, and the connecting-barl along the top, securing the heads H together. About the center of the height of the heads H are supported. the sliding parallel rods J, which extend, as shown, to support a circular saw K in suitable bearings at the `front and having pulleys L on each side ot fer to use double, as shown, though for li'ght workone belt would, l cousidenbe quitesut-l cient. The belts O, after passing over the pulleys L and N, respectively, at front and rear ends of the rods J, are then carried over guide-pulleys P, located,as shownover the centralopening of the frame D and close together at the center of said opening, so as to equalize the length of the belts O as nearly as possible and compensate for the various angles in Which'the pulleys L and N on the rods .I may be placed. Said guide-pulleys P are carried in suitable bearings secured to the frame D. The belts O are driven by the pul ley Q, carried on the main driving-shaft S, mounted in suitable bearings on the main tranne. To take up slack in the belts 0,'a tightener-frame R, hinged to the main frame A and located over the pulley Q, is provided, having a pulley or pulleys therein to ride on the belts O. The shaft S derives its motion from any suitable source of power. On the top of the front head H a scale of degrees, similar to the scale on the bearing C, is provided to read to each side of the center line, which indicates the vertical position of the saw K and which may be indicated by a pointer on the bearing.

To secure the heads H, rods J and mechanism carried thereby in position, as desired, a clamp-screw T is secured in the front bearing to engage the corresponding head H, a portion ot which extends Within said bearing. On one of the rods J an adjustable collar is provided to form a stop tov limit the travel of the rods .I forward, as may be necessary in certain work.

On the front of the main frameA is the elevating-plate U, sliding on suitable guide-rods a. To the back of `the elevating-plate U, a

journal-bearing b `is secured supporting a bevel-pinion c; which has an internally-screwthreaded hole through its center. Through this pinion c passes a screw d, attached to the main frame A atits lower end. A bevel-pinion e, operated by acrank-han dle or hand-.wheel f, engages with the bevel-pinion A@and conse-rl qnently by operating the said crank-handle the plate U may be elevated or depressed for the purpose of bringing the workwplacedo-n; the table j, hereinafter described, to the de-l sred relative height with respect to the saw K. On the front of .the .plate Ua, plate grisy movably supported on guide-rodsp. On one guide-rod p adjustable collars are provided to form stops to regulate the transverse inotionfth-e plate ga-lougthe; plate U.

The table y'. consists of two parts-hinged to-s getfherfat the center .of the upper edge of the plate g, on which it is supported. On each partof tfh'e table j-fa sector'c is: secured, having ascentral opening radial from the :hingeandA in which: suitable f clam pingsscre-w's Z-are provided to--clampthe fpart of the table fat; any desirediangle ofdescentnvhichy is denoted; by-scales of degrees si milar to t-'h'escales here: inbeforefreferred to. In the upper .edges 'of both the. plates .U and g are formed T-.channels, las -al means .byv'which -stops 'm' or :guide pieceszare secured to restthe :work against when being operated on. -To secure thefraine, Din'. any position, -a wedgev or keyffLa-vcon nectedt-o` the .pedal oby afrodh, having aspiral vspring q thereon, -is provided, -t'hfeikey u:

In order to take up 'any slack in the belts O, farther than is provided for by the tightener-frarne K, the bearings of the main shaft S may be made vertically adjustable.
